IMPROVEMENT IN I-IANDLES Foa FILES.

Specification forming part of Letters Patent No. 43,994, dated August30, 1864; antedated August I6, 1864.

To @ZZ whom, it may concern.-

Be it known th at I, G. F. HUNTER, of Adrian, in the county of Lenaweeand State of Michi gan, have invented a new and useful Improvement inFile-Handles; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

rJhis invention relates to that class of filehandles tha-t has to beused when the article to be tiled will not admit 0f the handle beingdriven directly on the shank of the file, reference being had to theaccompanying drawings and letters of reference marked thereon, withfigures numbering from l to 5, of which- Figure l is a perspective viewexhibiting its several parts, viz: lile A, clamps B B, bolts C and E,ferrule F, handle G, nut H, pivot D, recesses L L, and projections M M.Fig.2 exhibits the handle G reversed from its position seen in Fig. 1,and also exhibiting the dotted lines N`N. Fig. 3 exhibits the manner inwhich the bolt E passes through the handle G, and also the recesses L Land hole O in its head. Fig. 4exhibits one of the clamps B, removed fromthe handle G, exhibiting its projection M and holes O and P. Fig. 5exhibits the bolt C with its nut removed from the handle G.

The clamps B B are attached by means of the bolt C, passing through theholes O O seen in the center. lhe handles E and clamps B B are attachedby means of the pivot D, as is clearly seen in Figs. 1 and 2.

I will describe the operationv of my file-l handle as follows: When aperson wishes to attach it to a file, he turns the handle G on its pivotD to the position of the dotted lines N N, Fig. 2, which in turn allowsthe projection M ou the top of clamp B to drop into the recesses L L inthe head of the bolt E, which in turn opens the lower end of the clampsB B sufficient to slip on the shank of the file, then by turning thehandle G to the position seen in either l or 2 throws the projections MM out of the recesses L L, which spreads the tops of clamps B B apart,causing the lower ends to grasp the shanks of the file, all of which isclearly seen in Figs. l and 2.

After thus having described my invention, what I claim, and desire tosecure by Letters Patent, is

A file-handle constructed as above described, with its clamps B B, boltU, bolt E, and handle G, for the purposes set forth and described.

C. F. HUNTER.
